, p. 53 - 54 (1999)
The radical-mediated reactions of γ-hydroxy- and γ-alkoxy-α- methylenecarboxylic esters 3 (R1 = Ph, i-Bu, and t-Bu, R2 = H, Me, MOM, and MEM) with isopropyl iodide or cyclohexyl iodide performed in the presence of Lewis acids gave the syn-adducts 4 predominantly, whereas the anti-adduct 5 was the major product in the reaction of 3 (R1 = Ph, R2 = Me) with t-butyl iodide.
